HOT-AIR RADIATOR.

SFECIFICATION forming part of Letters Patent No. 461,484, dated October 20, 1891.

Application filed November 28. 1890.

To all whom it mag concern..-

Be it known that I, WILLIAM B. MUMFORD,

a citizen of the United States, residing at Kansas City, in the county of Jackson and 5 State of Missouri, have invented certain new and useful Improvements in Hot-Air Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to heating gas-stoves of the type in which cold air is admitted to the base of the stove or combustion-chamber, where it becomes heated and from which it passes through radiatingflues out into the room. t

It has-for its object to provide a stove of this character simple in construction, d urable in use, and comparatively inexpensive of production, and which may be readily transferred from one room toanother, owing to its lightness.

With these objects in view the invention consists in certain features of construction and combination of parts, which will be hereinafter described and claimed.

In the accompanying drawings, wherein like letters of reference indicate corresponding parts, Figure l is a side elevation of my improved stove, and Fig. 2 is a central vertical sectional View of the same.

A denotes the combustiomchamber, supported above the floor by legs a. This combustion-chamber is of conical form, enlarging from its base toward its upper end,and is provided with an inwardly-projecting flange a at its lower end and'at its upper end with shelves or brackets a B denotes a supporting-ring having a lateral flange b, which encircles and is secured to the combustion-chamber at its top.

Within the combustion-chamber and supported upon its base flange in a removable manner is what I term a conical draft'section, and which by tapering in an opposite direction leaves a space between it and the. combustion-chamber. The gas-burner, of any well-known or improved type, and which is end to plates G g, respectively,

shown in this instance as of circular form, is

'the plate toward its edge.

E denotes the radiator, which consists of a cluster of flues g, which are secured at each the plate 9 having a depending flange somewhat conical and is seated within the supporting-ring B. This radiator-section is also removable. The upper plate, to which the upper ends of the cluster of fines are secured, is provided with .an upwardly-extending flange to support a hood F, which has a depending conical top and outwardly-flaring sides. .To support this hood upon the top plate, I provide the interior of the hood with cross-straps having near their extremities shoulders f, which prevent the lateral accidental displacement of the hood. This construction, however, is immaterial, and other modes of attachment may be resorted towithout departingfrom the scope of my invention. To gain access to the I provide a door 0.

The operation is as follows: The gas is turned on and is ignited at the burner. The air now ascends the draft-section-, and, owing to the contracted mouth of this section, it is forced directly against the burner and into the flame. The heated air is now partially 9o retarded in its upward course by the plateD and is caused to circulate within the space formed between the combustion-chamber and the draft-section, and finally carried up through the perforations in the distributingplate, where it escapes into the drum X, formed by the plates g and ring B, from whence it traverses the radiating-pipes, meeting in its upward course the hood, which deflects it into the room. In the passage of the 100 combustion-chamber heated air from the combustion-chamber to the drum Xit Willbe noticed that it must pass through the distributing-plate, and in order to prevent it too rapidly passing through this plate I puncture the same with holes of different sizes, bringing the small holes at the center, Where the air would have the greater tendency to pass. It will therefore be seen when the hot air strikes the plate at its center only a portion thereof escapes through the small holes, While the greater portion, owing to the convexity of the plate and the grading of the holes, is distributed equally, so that it escapes through the plate into the drum evenly.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of this invention Will readily appear. It will be noticed that the parts are not secured together by either rivets or solder, but are simply one supported upon another, Which enables me not only to furnish to the trade parts which have become damaged or Worn and which may be readily set in place by the user, but at the same time enables me to pack the sections more compactly for shipment. The gain in radiating-surface which I attain by this improved construction is also an important feature.

Having thus described my invention, I claim- 1. In combination, a combustion-chamber open at each end, a conical draft-section located therein, a gas-burner, a cluster of openaended radiating-t-ubes communicating "With said combustion-chamber, and a perforated distributing-plate interposed between the lower ends of the tube and the burner.

2. In combination, a combustion-chamber provided with an inlet and outlet opening, a draft section provided With a contracted mouth, a burner arranged above said draftsection, a cluster of radiating-fines communicating with saidcombustionchamber, and a convex perforated distributingplatelocated between the burner and the cluster of tubes and having the apertures varyingin size from \VILLIAM B.
